SEE-GIFICATION forming part of Letters Patent No. 684,220, dated October 8, 1901.

Application led July 18, 1901. Serial No. 68,713. (No model.)

To all whom it may con/cern:

Beit known that I, HENRY GIBBS, a resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Spray-Nozzles, of which the following is a full, clear, and exact description. Y

This invention has for its object to provide an improved construction of spray-nozzle that may be readily attached to a lawn-sprinkler or may be detached therefrom and may be connected to an ordinary coupling of a hose, so that the spray-nozzle may be used either in connection with stationary sprinklers or as a nozzle for the end of a hose.

The invention consists in the features of improvement hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claim at the end of this specification.

Figure 1 is a view in elevation, showing a lawn-sprinkler having my invention applied thereto. Fig. 2 is a view showing my improved nozzle applied to the end of a hose to be used by hand. Fig. 3 is a detail plan view of the nozzle with the top removed. Fig. 4 is a detail side view of the nozzle with the top removed. Fig. 5 is a view in central vertical section through the nozzle complete.

A designates an ordinary hose-stand, to which is connected a. coupling B, having a threaded end lat-hat will be united to the hose, and having an upper threaded end o', to which my improved spray-nozzle will be attached. The spray-nozzle comprises a base-section C and a detachable outer portion D. The basesection C is provided upon its interior with threads c to engage the threaded upper end b' of the coupling B or to engage the threaded end e of a coupling at the end of the hose E. Hence it will be seen that the nozzle can be readily used either in connection Ywith a sprinkler-stand or can be detached therefrom and attached directly to the coupling at the end of the hose when the operator desires to direct the spray by hand. The base C of the spray-nozzle is formed with a reduced chainfa bered extension C', having exterior threads o' to engage a thread cl upon the interior of the section D of the noz'zle. In the extension C are formed two openings c2 and c3, from which lead spirally disposed grooves o4. When the extension is in position within the outer section D of the nozzle, the wall of the section D coming opposite the holes c2 and c3 and spiral channel c4 will cause the water as it passes through these holes and channels to take a spiral coursebeiore it enters the chamber at the end of the section D. This chamber is provided With an inwardly-extending ange d', and as the water enters the chamber of the section D and strikes the dange d with a whirling motion it is caused to pass through the orifice cl2 in finely-divided form or spray.

One advantage in forming the spray-nozzle of the sections C and D is that the extension C,with the holes c2 and c3 and channel o4, may be readily cast, and the cost of the nozzle is thus reduced to a minimum. So, also, if any stoppage occurs in the nozzle it can be readily removed by unscrewing the outer section D from the section C.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, ism

A spraynozzle formed of sections C and D;

the section C being provided at its base with an interiorly-threaded portion adapted to admit the threaded coupling of a sprinkler or of a hosepipe and being formed withathreaded extension C having holes and spiral grooves therein, and an outer section D interiorly Witnesses: l'
